Question

Example 2 Shown below is a side-by-side view of two long straight wires that are parallel to one another. One W current Io down the page, the other carries an equal current lo up the page. o) (3 tonn In the diagram above, draw a vector j point P representing the magnetic field due to the current traveling upward and label it Bap. Do the same for point Q. Then draw a vector just below point Prepresenting the magnetic field due to the current traveling downward and label it Baowa. Do the same for point Q. Then draw a vector just below point Prepresenting the total magnetic field and label it B. Do the same for point Q. The current through each wire is L-5 A, and the distance between point P and each of the wires s 0.01 m. Also, the distance between point Q and the downward current is 0.01 m. (b) Determine the magnitude of Bap due to the upward current at point P. Then determine the magnitude of to the downward current at point P. Next, determine the magnitudes and Baerne at point Q.

Explanation / Answer

Right hand rule is used to find the direction of induced current.

So if you are using right hand rule here, it's wrong.

Use Fleming's left hand rule to find the direction of magnetic field.
